IKB

法国著名艺术家伊夫·克莱因以“国际克莱因蓝色”和他的单色作品而闻名。

克莱因的蓝色获得了一个专门说法，叫做International Klein blue，简称IKB

1957年，法国人伊夫·克莱因（YvesKlein）在米兰举行画展，展厅里悬挂着八副同样大小的画板，上面涂满了群青色，从此，这种色彩被正式命名为"国际克莱因蓝"（InternationalKleinBlue）。

In 1947, Klein began making monochrome paintings, which he associated with freedom from ideas of representation or personal expression. A decade later, he developed his trademark, patented colour, International Klein Blue (IKB). This colour, he believed, had a quality close to pure space, and he associated it with immaterial values beyond what can be seen or touched. He described it as ‘a Blue in itself, disengaged from all functional justification’. Klein made around 200 monochrome paintings using IKB. He did not give titles to these works but, after his death, his widow assigned a number to each one
